a. matter
b. mass
c. weight
d. gravity does not change
e. determined by gravity
f. location determines amount
It's kind of hard for me to explain but to further understand this topic you can google the deference between mass and weight. Both mass and weight are both related to matter to that's why matter is a.
Weight is determined by gravity because you would way less on the moon that doesn't have that much of a gravitational pull. That's why people jump really high on the moon. that's also why the location determines the amount.
Mass however doesn't change by gravity. When you go to the moon you do not loose more of yourself or become smaller, you stay the same size. That is part of mass.
False, science can experience change
Answer:
0.7864m
Explanation:
Ignore air resistance (the ball's horizontal speed stays constant), the time it takes for the ball to travel 1.95 m horizontally at the rate of 4.87 m/s.
t = 1.95 / 4.88 = 0.4s
This is also the time it takes to fall vertically with gravitational acceleration of g = 9.81 m/s2. We can use the following equation of motion to estimate the vertical distance:
By Newton's 3rd law: That for every action there is an equal and opposite reaction.
So if force on one mass is 4N, then the force on the other mass is -4N.
